The MM-PSF is an embedded isolated power supply by MicroMax Computer Intelligence, designed specifically for РС/104 systems.

It provides a РС/104 system with 12V, 5V and 3.3V DC output voltages. The combined power of the device is up to 60W.

The power supply features reverse polarity protection and transient voltage surge suppression. The MM-PSF has advanced electromagnetic compatibility (MIL-STD-461F compliant).

The output power is supplied to latching connectors, as well as to system buses PCI-104 and PC/104. The device features short circuit protection with no time limit. As soon as the connection is recovered, the MM-PSF restores power supply automatically.

The MM-PSF is designed in compliance with vehicle standards MIL-STD-1275D and MIL-STD-704F.
